Title: Coated optical fiber with colored layer
Inventor: MAEDA KEIGO
IPC: G02B6/44
Filed: 1991-06-21
Abstract: PURPOSE:To produce the coated optical fiber having <=180mum outside diameter by coating a colored layer in common use as a protective layer on the outer periphery of a primary layer by omitting a secondary layer. CONSTITUTION:The primary layer 2 consisting of a UV curing resin having a low Young's modulus is provided at >=15mum thickness on the outer periphery of the optical fiber 1 having 125mum diameter. The colored layer 5 consisting of a UV curing resin having the high Young's modulus in common use as the protective layer is coated on the outer periphery thereof with <=180mum outside diameter. Namely, the side pressure characteristic or a transmission loss of the coated optical fiber having <=180mum outside diameter depends more on the thickness of the primary layer 2 than the secondary layer and, therefore, the side pressure characteristic does not degrade even with the coated optical fiber having the colored layer 5 in common use as the thin protective layer. The coated optical fiber which has the two-layered structure without having the secondary layer and is provided with the colored layer having <=180mum outside diameter is obtd.

Title: Display device
Inventor: SASUGA MASUMI
IPC: G09F9/00
Filed: 1989-06-15
Abstract: PURPOSE:To relieve the stress occurring in the difference in coefft. of expansion between a liquid crystal display panel and driving wiring part and to prevent the disconnect of leads at the time of automatic bonding of tapes by using an elastic member to constitute the driving wiring part of the liquid crystal display panel. CONSTITUTION:A video signal driving circuit is divided to upper and lower two groups which are mounted on FPC (flexible printed circuit) substrates 10a, 10c. A vertical scanning circuit is also mounted on the FPC substrate 10b. Since the driving wiring part of the liquid crystal display panel 5 is constituted of the FPCs 10a to 10c consisting of the elastic member, such as polyimide, the stresses generated in the major axis direction of the FPCs by the difference in the coefft. of expansion between the liquid crystal display panel 5 and the FPCs are absorbed by the deflection of the resislient FPCs 10a to 10c. The cutting of an input side outer lead 14 which is weakest in strength of a TAB 9 is, therefore, prevented and the reliability of the liquid crystal display device on heat is improved.

Title: Image forming device
Inventor: TAKAHASHI TOMOKO
IPC: H04N1/19
Filed: 1991-06-21
Abstract: PURPOSE:To prevent the deterioration of an image caused by a breakage per light emitting element to extend the life of total light emitting elements. CONSTITUTION:An LED array 3 has an element density higher than the density of image data to be written. A plurality of LED elements are available for writing image data for one pixel. In addition, a light emitted from one LED element is adjusted by an image forming member 2 so that the area for a plurality of elements can be exposed to the light on a photosensitive body 1. Image data for one dot is recorded using a part of a plurality of LED elements, e.g. two of three elements. Light emitted from the LEDs is reflected by a spread mirror 5, and the intensity of the light is detected by a light emission detector 4. If abnormal elements exist, the elements are changed over to normal elements. Therefore, the array is improved in life, and the writing function as an array is not deteriorated even if a part of the elements is broken.

Title: Golf putter with face part very low in restitution performance
Inventor: HIROTA ATSUO
IPC: A63B53/04
Filed: 1998-04-22
Abstract: PROBLEM TO BE SOLVED: To facilitate putting and to reduce the mental burden of a golfer by devising the characteristic of a face part. SOLUTION: The face part of a putter head main body 2 is made of a member 1 with a very low coefficient of restitution. Therefore the velocity vector VR of a ball relative to a putter head becomes so small that the direction of the grounding velocity vector VE of the ball approximates the direction of the grounding velocity vector VP of the putter head; that is, the direction in which the ball is shot approximates not the direction perpendicular to the putter face but time direction in which the head is moved, so that a golfer is required only to move the putter head in the desired direction without caring for the direction of the face, leading to remarkably enhanced putting directivity. Moreover, since restitution performance is very low, hitting is ensured and the need for subtle touch can be eliminated. As a result, putting becomes very easy.

Abstract: PROBLEM TO BE SOLVED: To provide a wire stripper applicable to weight balance, strength and error in accuracy in an attempt of lightening weight by adopting resin. SOLUTION: Each base part of a pair of stripper bodies 2, 3 and each arm part 4a, 5a of a pair of handles 4, 5 are provided pivotally to the right and left directions with a common pivotal supporting pin 6. A movable gripping bit 15, which grips an electric wire 49, is provided so as to be enabled to slide and the movable gripping bit 15 is connected to the one of the handles above, handle 4, with a linking part 16. Then, a fixed bottom blade 20 is secured to a supporting part 13' and a movable upper blade 22, which cuts and peel off the cover 49a of the electric wire 49, is provided so as to be enabled to slide.  When the wire stripper 1 is structured with the movable upper blade 22 connected to the other handle 5, the bodies 2, 3 and each handle 4, 5 of a resin material are used, while the movable gripping bit 15, the fixed bottom blade 20, the movable upper blade 22 and the linking parts 16, 23 all made of metal are used. This makes the center of gravity G of the wire stripper 1 positioned closer to the pivotal supporting pin 6 compared with the stripper entirely made of metal.

Title: Video tape-recorder
Inventor: TANAKA TOMOSHI
IPC: G11B5/027
Filed: 1997-06-09
Abstract: PROBLEM TO BE SOLVED: To provide a video tape-recorder which appropriately reproduces required vocal sound by the ordinary method. SOLUTION: Inputted vocal signals are continuously written into memory 32 by a memory control circuit 28 to be updated on demand. When an alarm is inputted, the memory control circuit 28 suspends the write of vocal signals after a specified period of time is elapsed and reads the vocal signals before and after alarm generation from the memory 32 at the interval of two fields. Since a video tape 20 is intermittently driven at an interval of two fields, vocal signals read from the memory 32 are continuously recorded into the video tape 20. By this, vocal signals before and after alarm generation are recorded into the video tape at an interval of two fields and thereby required voice is appropriately reproduced at the normal mode.

IPC: F02D9/02
Filed: 1997-06-09
Abstract: PROBLEM TO BE SOLVED: To provide a compact accelerator device in which operability of an accelerator pedal can be improved in simple constitution. SOLUTION: A support 40 is disposed on the inner circumference of an outer spring guide 30 at which an outer spring 60 and an inner spring 65 interlocked with an accelerator lever 20 connected to one end side of an accelerator shaft 3 to rotate to generate urging force in an accelerator closing direction to be positioned and fixed to a housing 1. On the inner circumference of the support 40, an inner spring guide 50 is disposed to be interlocked with the outer spring guide 30 to rotate. As the accelerator lever 20 is rotated, friction force is generated between the outer spring guide 30 and the support 40, and between the inner spring guide 50 and the support 40.  This friction force becomes larger as the outer spring 60 and the inner spring 65 rotate in an accelerator opening direction by radial direction partial force of spring torque reaction in a twisting direction of the outer spring 60 and the inner spring 65.
